A mixture of 4-chloro-7-(2-(imidazol-1-yl)ethoxy)-6-methoxyquinazoline (49 mg, 0.16 mmol) and 3-hydroxyaniline (21 mg, 0.19 mmol) in isopropanol (3 ml) and isopropanolic hydrogen chloride (0.2 ml of a 5M solution) was stirred at 80° C. for 1 hour. The precipitated solid was collected by filtration, washed with isopropanol and ether and dried under vacuum to give 4-(3-hydroxyanilino)-7-(2-(imidazol-1-yl)ethoxy)-6-methoxyquinazoline hydrochloride (56 mg, 93%). 1H NMR Spectrum: (DMSOd6; CF3COOD) 4.01(s, 3H); 4.64(t, 2H); 4.78(t, 2H); 6.71(d, 1H); 7.1(m, 2H); 7.28(t, 1H); 7.41(s, 1H); 7.74(s, 1H); 7.83(s, 1H); 8.21(s, 1H); 8.87(s, 1H); 9.22(s, 1H) MS-ESI: 378 [MH]+
